Farmers of Palpa are earning thousands from commercial cultivation of amriso or broom grass. Amriso grows well even in rocky landscapes, requires minimum investment and has a good market. Amriso is mostly used to make brooms as well as for fodder and firewood. The Forestry Office in Tansen is organising a campaign to declare Palpa an 'Amriso District' and has been promoting amriso plantations in government premises, private forests and along roadsides.

The district office had planted 19,000 Amriso saplings five years ago. Not only has Amriso improved the livelihood of local farmers but also helped in conserving the soil and increasing greenery.

"Rs 20 million worth of amriso was exported from the district last year," Rambabu Paudel of Forestry Office said. "Some farmers are earning upto Rs 300,000 from amriso alone."
